Step 1: Let's Learn

Read it, or press Listen and follow the words.

Equals does not mean "the answer is". It means the same amount as.

Equals (=) means both sides are worth the same.

Like a see-saw

Both sides must weigh the same. 4 + 2 = 6 balances.

4 and 2 makes 6.

Second part2

It can go either way round

9 = 6 + 3 is true. The total is allowed to come first.

Second part3

Equals is not "the answer is"

It means both sides are worth the same. That is why 5 = 3 + 2 is perfectly correct, even though the sum is on the right.

Think of a balance

If the two sides weigh the same, it balances. Change one side and you must change the other, or it tips.

Step 2: Try It Yourself

Change a side and see if it balances.

Change the parts. The total keeps both sides the same.

3 and 4 makes 7.

Step 3: Watch an Example

One step at a time.

Watch Ben Check a Sentence

Ben sees 5 + 2 = 8 and wonders if it is true.

  1. Step 1

    He works out the left side: 5 and 2 makes 7.

Step 4: Your Turn

Practice makes it stick.

Checking Work

Problem 1 of 1

Is this sentence true? 3 + 4 = 7

True or False?

Work out both sides, then decide.

1 of 3

Is 6 = 6 true?

2 of 3

Is 8 = 5 + 3 true?

3 of 3

Is 4 + 3 = 8 true?

Step 5: Quick Check

Show what you know.

Question 1 of 2

What does the equals sign mean?

Question 2 of 2

Is 10 = 7 + 3 true?

What You Learned

  • Equals means the same amount as.
  • It does not mean "the answer is next".
  • The total can be written first: 9 = 6 + 3.
